Title
(EN) STEERING ASSEMBLY FOR DIRECTIONAL DRILLING OF A WELLBORE
(FR) ENSEMBLE DE GUIDAGE POUR FORAGE DIRECTIONNEL D'UN TROU DE FORAGE
Abstract
(EN)
A steering assembly includes a housing having a longitudinal axis, a mandrel having a front connecting extremity and a rear connecting extremity, the mandrel passing through the housing and arranged in a first position coaxially to the longitudinal axis of the housing, a deflector device configured to exert a side force on the mandrel to offset the front connecting extremity of the mandrel from the longitudinal axis, and a tool face assembly configured to rotate the front connecting extremity of the mandrel in a desired direction.
(FR)
L'invention concerne un ensemble de guidage comprenant une enveloppe comportant un axe longitudinal, un mandrin comportant une extrémité de liaison avant et une extrémité de liaison arrière, le mandrin traversant l'enveloppe et étant agencé dans une première position de manière coaxiale par rapport à l'axe longitudinal de l'enveloppe, un dispositif déflecteur conçu pour exercer une force latérale sur le mandrin de sorte à décaler l'extrémité de liaison avant du mandrin par rapport à l'axe longitudinal et un ensemble face d'outil conçu pour faire tourner l'extrémité de liaison avant du mandrin dans une direction souhaitée.
